While I have difficulty finding the site I originally got the numbers from, I think the FS at this point of the timeline has somewhere in the ballpark of 120-150 RCTs, in total, with their ability to increase those numbers severely limited by their economy and industry. By contrast, we could currently stand up about 77 Armies - or ~770 RCTs' worth - of conventional troops in total before we hit our peacetime recruitment limit of 1% of our population.
You know something I linked that mentioned is supply. We have never fought a war for more then a single turn with out full military might behind it. Not have we truly supplied a massive military for a long time.
If we did somehow raise over 77 armies, if they all went into battle and loses started to mount in terms of parts and ammo, we most likely wont be able to maintain them all for long.
That's out biggest threat, we can slap an enemy across the face, but even at max production we can't maintain that momentum for long as attrition sets in and production falls behind the need for replacement.
Weirdly we end up in the same situations that clans did, even with perfect supply limes, they just can't produce enough material to replace what's lost.
Going to the RCT comparison. 77 armies would cost, in comparison to the other factions, would cost 6,160 rp to maintain...in peacetime. That number increases to an amount that I won't even place here when even 10 are in combat. For comparison, right now each successor state should easily have 2000 rp or more each, baring the cappelans. And each spend roughly 2/3ds of that on military alone.
So you except me to believe that somehow, Helghan alone has enough RP to raise that 77 armies, and then somehow have rp left over to do other projects, and then send out a drawn out protracted campaign?
Now this game works on an AP system so conversion is hard, however I bring this up since RP is the closest metric we have to quantify the Great houses scale of economy without the chaft.
I would do math but, its 11 pm so ill just drop the chart so you can do some math your on the costs of the IS militaries, and of our own. It gets crazy once you start to try and figure out how much Helghan must make in RP per year.
Its a rabbit hole that gets very crazy the higher you go on it.
